Answer:
The $6.03 for 7 bags of ice is a better deal
Step-by-step explanation:
In order to find out which is a better deal we find the unit price.
To find the unit price we do the cost divided by how many bags of ice.
6.02 divided by 7 = 0.86, so the unit price is 0.86/1
5.52 divided by 6 = 0.92, so the unit price is 0.92/1
Finally, we can see which has a lower unit price which is the $6.03 for 7 bags of ice
Two trains leave Evas station 70 minutes apart. Train X leaves first at 1:15 pm and heads west at a speed of 106 km/h. Train Y leaves later and travels directly north at a speed of 128 km/h.
a) How far apart are these trains (along a hypotenuse) at 4:05 pm?
b) If Train Y has an unplanned stop that lasts 24 minutes, how far apart should these two trains be at 5:50 pm?
c) If both trains turn around and head back to Evas station, with Train X travelling at a new average speed of 142 km/h, which one will arrive first? Show your work and explain your thinking.
Train X is 374.39 km far apart from train Y (along the hypotenuse) at 4:05 pm and 627.009 km far apart (along the hypotenuse) at 5:50 pm.
Define hypotenuseIt goes without saying that the side opposite the right angle is the hypotenuse of a right triangle. This side of a right triangle is the longest.
given: Train X travels at a speed = 106 km/h
Train X started moving on 1:15
Train Y travels at a speed = 124 km/h
Train Y started moving on 2:25 pm
a) Time taken by train X = 2 h 15 min = 2.83 h
Speed = 106 km/h
Distance = speed * time
Distance = 106 * 2.83
Distance travelled by train X towards west is 299.98 km.
Time taken by train Y = 1 h 45 min = 1.75 h
Speed = 128 km
Distance = speed * time
Distance = 128 * 1.75
Distance travelled by train Y towards north is 224 km.
By using Pythagoras theorem,
(299.98)² + (224)² = hypotenuse²
89988 + 50176 = hypotenuse²
Hypotenuse = 140164 = 374.39
Therefore, distance between train X and train Y at 4:05 pm along hypotenuse is 374.39 km.
b) Time taken by train X = 1 h 45 min = 1.75 h
Speed = 106 km/h
Distance = speed * time
Distance = 106 * 1.75
Distance travelled by train X is 185.5 km.
Total distance travelled by X = 299.98 + 185.5 = 485.48 km
Time taken by train Y = 1 h 21 min = 1.35 h
Speed = 128 km
Distance = speed * time
Distance = 128 * 1.35
Distance travelled by train Y is 172.8 km
Total distance travelled by Y = 224 + 172.8 = 396.8 km
By using Pythagoras theorem,
(485.48)² + (396.8)² = hyopotenuse²
235690.84 + 157450.24 = hypotenuse²
393141.08 = hypotenuse²
Hypotenuse = 627.009
Distance between train X and train Y at 5:50pm is 627.009 km.
c) Distance of train X from Evas station = 485.48km
Speed = 142 km/h
Time taken = distance / speed
Time taken = 485.48 / 142
Time taken by train X to reach station is 3.42 h
Distance of train Y from Evas station = 396.8 km
Speed = 128 km/h
Time taken = distance / speed
Time taken = 396.8 / 128
Time taken by train Y to reach station is 3.1 h
Therefore, train Y will arrive station first.

Marbles, and 4 green marbles. The second bag contains 3 red marbles,2 blue marbles, and 4 green marbles. Aakesh will randomly select one marble from each bag. What is the probability that Aakesh will select a blue marble from each bag ?
The probability that Aakesh will select a blue marble from each bag is 4/45.
To find the probability that Aakesh will select a blue marble from each bag, we need to calculate the probability of selecting a blue marble from each bag and then multiply those probabilities together.
Let's start with the first bag, which contains 5 marbles: 2 red marbles, 2 blue marbles, and 1 green marble. The probability of selecting a blue marble from the first bag is:
P(Blue from first bag) = Number of blue marbles / Total number of marbles in the first bag
P(Blue from first bag) = 2 / 5
Now, let's move on to the second bag, which contains 9 marbles: 3 red marbles, 2 blue marbles, and 4 green marbles. The probability of selecting a blue marble from the second bag is:
P(Blue from second bag) = Number of blue marbles / Total number of marbles in the second bag
P(Blue from second bag) = 2 / 9
To find the probability of both events happening (selecting a blue marble from each bag), we multiply the individual probabilities together:
P(Blue from both bags) = P(Blue from first bag) * P(Blue from second bag)
P(Blue from both bags) = (2 / 5) * (2 / 9)
P(Blue from both bags) = 4 / 45.

Answer:
C
Step-by-step explanation:
cot²θ = 1/tan²θ
plug this in to get
1/(1/tan²θ + 1)
1/tan²θ + 1 = 1/tan²θ + tan²θ/tan²θ = (1+tan²θ)/tan²θ
we then have
1/((1+tan²θ)/tan²θ)
1/(x/y) = y/x, so this is equal to
tan²θ/(1+tan²θ)
tan²θ = sin²θ/cos²θ, so plug this in to get
(sin²θ/cos²θ)/(1+sin²θ/cos²θ)
1+sin²θ/cos²θ = cos²θ/cos²θ + sin²θ/cos²θ
sin²θ + cos²θ = 1, so we have
(cos²θ+sin²θ)/cos²θ = 1/cos²θ. plug this in to get
(sin²θ/cos²θ)/(1/cos²θ)
(a/b)/(c/d) = (d/c) * (a/b), so we have
(sin²θ/cos²θ)/(1/cos²θ) = cos²θ/1 * sin²θ/cos²θ = sin²θ

What is a rotation?In Mathematics and Geometry, a rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.
Next, we would apply a rotation of 90° clockwise about the origin to the coordinate of this triangle NOG in order to determine the coordinate of its image;
(x, y) → (y, -x)
Point N = (-4, -1) → Point N' (-1, 4)
Point O = (-4, -3) → Point O' (-3, 4)
Point G = (0, -1) → Point G' (-1, 0)

The average rate of growth for human hair is about 0.3 millimeters per day. How many days will it take a hair that is 12 millimeters long to grow to be 16.5 millimeters?
It will take 15 days for the hair to grow from 12mm to 16.5mm
What do you mean by average rate?By "average rate" in this context, we mean the typical or usual amount of hair growth per unit of time, which is often measured in millimeters per day. This rate can vary slightly depending on factors such as age, gender, genetics, diet, and overall health.
Let's first find out how much the hair needs to grow by subtracting its initial length (12mm) from its target length (16.5mm):
16.5mm - 12mm = 4.5mm
Now we can divide this growth by the average rate of hair growth to find the number of days it will take to grow this much:
4.5mm ÷ 0.3mm/day = 15 days
Therefore, it will take 15 days for the hair to grow from 12mm to 16.5mm.

By using graphical method, find optimal solution of the problem max z = 3x + y s.t 2x - y ≤ 5 -x + 3y ≤ 6 x ≥ 0, y ≥ 0
By analyzing the graph and evaluating the objective function at each vertex of the feasible region, we can find the optimal solution, which is the vertex that maximizes the objective function z = 3x + y.
To find the optimal solution of the given problem using the graphical method, we need to plot the feasible region determined by the given constraints and then identify the point within that region that maximizes the objective function.
Let's start by graphing the constraints:
1. Plot the line 2x - y = 5. To do this, find two points on the line by setting x = 0 and solving for y, and setting y = 0 and solving for x. Connect the two points to draw the line.
2. Plot the line -x + 3y = 6 using a similar process.
3. The x-axis and y-axis represent the constraints x ≥ 0 and y ≥ 0, respectively.
Next, identify the feasible region, which is the region where all the constraints are satisfied. This region will be the intersection of the shaded regions determined by each constraint.
Finally, we need to identify the point within the feasible region that maximizes the objective function z = 3x + y. The optimal solution will be the vertex of the feasible region that gives the highest value for the objective function. This can be determined by evaluating the objective function at each vertex and comparing the values.
Note: Without a specific graph or additional information, it is not possible to provide the precise coordinates of the optimal solution in this case.

A new cylindrical can with a diameter of 4cm is being designed by a local company. The surface area of the can is 140 square centimeters. What is the height of the can? Estimate using 3.14 for pi and round to the nearest hundredth. Apply the formula for the surface area of a cylinder SA=2B+Ph
The height of the can of cylinder shape is 9.14 cm.
What is a cylinder?
In mathematics, a cylinder is a three-dimensional solid that maintains two parallel bases separated by a curved surface at a specific distance. These bases frequently have a circular shape (like a circle), and an axis connects their respective centres.
We are given the diameter as 4 cm.
So, the radius is 2cm.
Also, it is given that the surface area of the can is 140 square centimeters.
So, using the surface area of cylinder, we get
⇒Area = 2πr (h + r)
⇒140 = 2π * 2 (h + 2)
⇒140 = 4π (h + 2)
⇒140 = 4 * 3.14 * (h + 2)
⇒140 = 12.56 * (h + 2)
⇒11.14 = h + 2
⇒h = 9.14
Hence, the height of the can of cylinder shape is 9.14 cm.

During halftime of a football game, a sling shot launches T-shirts at the crowd A T-shirt is launched from a height of 6 feet with an initial upward velocity of 72 feet per second Use the
equation h(t) = -16 +72t+6, where t is time in seconds and h(t) is height. How long will it take the T-shirt to reach its maximum height? What is the maximum height?
Answer:
Hope this helps ;)
Step-by-step explanation:
To find the time it takes the T-shirt to reach its maximum height, we need to find the value of t when the velocity of the T-shirt is zero, because at this point the T-shirt has reached its maximum height and starts falling back down. We can find the velocity of the T-shirt by taking the derivative of the height equation with respect to time:
v(t) = h'(t) = 72
The velocity of the T-shirt is a constant 72 feet per second, so it will never reach a velocity of zero and will never reach its maximum height. The T-shirt will keep going up indefinitely.
If the problem had specified that the T-shirt was launched with an initial upward velocity of -72 feet per second (meaning it was launched downward), then we could have found the time it takes the T-shirt to reach its maximum height by setting v(t) = 0 and solving for t. In this case, we would find that t = 1, so it would take the T-shirt 1 second to reach its maximum height. The maximum height would be h(1) = -16 + 72(1) + 6 = 62 feet.
